Flagged prefixes
| Prefix | Family | Addresses | Country | Flags |

| 137.164.40.24/30 | IPv4 | 4 | US | Too specific |
| 205.154.246.160/27 | IPv4 | 32 | US | Too specific |
| 205.154.246.192/26 | IPv4 | 64 | US | Too specific |
A flag is an observation, not an accusation. Very large and very specific prefixes are both legitimate in the right context.
